I have an issue with weird seams showing up on my ZBrush displacements whenever I export them to Modo. I’ve tried GUV, AUV and PUV tiles, always remembering to flip the alphas before export, but I keep getting the same problem.

Does anybody have any idea what could be causing this, or a way to fix it?
This is using ZBrush 3.12 and Modo 302
